Blizzard apparently refused dissatisfied Korean gamers refunds based on sales contract agreements, and the FTC is looking into whether or not those contracts are unfairly keeping gamers from getting their money back after they discover problems with the game.

Korea is a massive market for Blizzard, so this could be a big deal if the FTC uncovers wrongdoing on Blizzard’s behalf. It’s an interesting move, and could have implications for the way companies are forced to handle consumer complaints in the future. After Diablo 3 got up and running, it became accepted wisdom that Blizzard was going to come out of the debacle a little embarrassed but otherwise strong. Legal action, however, could make this an entirely different matter.
